McAlindon, Peter and Lee, Gene C. (1995): Perceived Workload between the Keybowl and the QWERTY Keyboard. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 292-296.

“The Keybowl alphanumeric input device was designed and developed to totally eliminate finger movement and drastically reduce wrist motion. Typing without finger movement requires a typist to adapt to a new method of key activation. This new method requires new mental, physical, and temporal demands, associated with new levels of performance, effort, and frustration. Together these requirements are measured to produce an overall measure of workload. Keybowl workload requirements are somewhat different than QWERTY keyboard workload requirements. With the significant reduction of finger and wrist motion comes concern over how much workload is expected in re-learning to type with the Keybowl. Typing workload was analyzed via the NASA Task Load Index. Typing workload analyses were performed to determine how the two groups of subjects (Keybowl and QWERTY) compared in terms of overall workload.”

McAlindon, Peter, Stanney, Kay and Silver, N. Clayton (1995): A Comparative Analysis of Typing Errors between the Keybowl and the QWERTY Keyboard. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 635-639.

“The Keybowl keyboard is the first known keyboard alternative to totally eliminate finger movement and drastically reduce wrist motion. With the significant reduction of finger and wrist motion comes concern over where the repetitive forces are being transferred. In typing with the Keybowl, biomechanical requirements are somewhat different than those in using a QWERTY keyboard. One way to help determine how well typists perform biomechanically is through keystroke error analysis. Typing performances were therefore analyzed via keystroke errors to determine if Keybowl "key" activation was different from QWERTY key activation. An error analysis for each character, hand, and gender was performed. This analysis has built a foundation for comparing two very different types of upper extremity motions and how they might affect a proficient QWERTY typist's performance in typing with the Keybowl.”
